CVE-2026-9016Network attack vector

Unauthenticated log forgery via public nonce

Published Jun 6, 2026 · Updated Jun 6, 2026

Log injection in Bowo Debug Log Manager 2.5.0 and earlier allows remote attackers to forge WordPress debug log entries. The unauthenticated log_js_errors AJAX handler accepts attacker-controlled message, script, lineNo, columnNo, and pageUrl values after checking only a nonce exposed by wp_localize_script in front-end HTML. JavaScript error logging must be enabled, and successful exploitation can fabricate incident records and hide activity in misleading log noise.
